A family consists of six member's P, Q, R, S, T and U. There are two married couples. Q is a doctor and the father of T. U is grandfather of R and is a contractor. S is grandmother of T and is a housewife. There is one doctor, one contractor, one nurse, one housewife and two students in the family. What is the profession of P?

Q, the doctor,is the father of T. S, the housewife, is the grandmother of T and hence the mother of W. Since there are only two married couples one being that of Q, the grandfather of R i.e. U must be married of S. Thus, R and T will be both children of Q and these must be the students. So, P, who remains, shall be the wife of Q and she alone can be the nurse. Thus, U must be the contractor. P is the nurse..

20 women can do a work in 15 days and 15 men can complete a work in 12 days. What is the ratio between the capacity of men and women?

(20*15) women can do a work in 1 day.

So women 1 day =1/300

(15*12) men can do a work in 1 day

So men 1 day work=1/180

So, required ratio=(1/300)/(1/180)

=(1/5)/(1/3)

=3/5

Adina, Julius, and Tia volunteered to read to children at the public library. Julius worked 2 hours less then Tia. Adina worked twice as many hours as Julius. All together they worked 58 hours. How many hours did Adina work?

If Tia work :x hrs

Julius work :X - 2

Andera work :2 ( x -2)

then ,

X +( X - 2) + 2( X - 2) = 58

X = 16

Andera work: 2( x - 2)

2(16 -2) = 28 hours
